Yeah, I do. But such 'trying to check whether I hear something or not' usually results in me thinking that it's okay.

Anyway, you know Polish pronunciation well, if you think something is being pronounced in a weird way, you can safely presume that your intuition is right and the voice may be a bit wrong. I think the only big surprises are three words (and their forms) written with rz but pronounced with r and z like separate sounds: Tarzan (the character), marznąć (to be cold) and its quite numerous forms, and mierzić (to disgust, sicken) - here it's r and zi separately.
